Think about technological advancement - from horse carriages and bicycles to trains, trams, cars ... self driving cars are here although they need a lot of improvement and safety testing. The vehicle that excites me the most is hyperloop. 700mph in a tube. Dubai is building one and I can't wait to see it. But for now, I can only post photos from Fort Edmonton Park in Canada and Alberta Aviation Museum. These vehicles were once groundbreaking, too.
